This is one of the very best places to go for excellent work. Jay van Dyke has to be one of the most knowledgeable engine builders Ive ever known.

Great people & enjoyed their honesty with my questions.

Great people that do great work!

Very well run shop great management they know what theyre talking about whether its old or new they got you covered they went out of their way to make sure the job I needed to be done was done fast and right I would definitely recommend this place just wish I knew about this place before

If you want to know about engines. Dont go to Napa. Go to people who know engines. People who do it everyday. Not, people who speculate how it should be done. Arnie knows his stuff. This is his profession. He is a professional. And he will help you.

Fantastic crew, great prices and Quality work!!

Thanks for the boring on golf cart runs better than new

Very knowledgeable people, say service. Highly recommended.

Responsive, easy to work with, very knowledgeable, nice and trustworthy. Looking forward to being a returning customer!

Arnie, is just one of those guys you want for your builds. We run rice and that market is difficult and just like any sport is costs money to go fast and keep it together.We are fortunate enough to have a great business to coordinate with. Excellent garage clean and they have the right equipment.

Right place

Very helpful and informative!!

Arnie is a great guy with a ton of knowledge. Very friendly and professional. There is a reason all the race guys bring their business here. I will be back for my next build.

Arnie is the man. He has been in this same location for over 30 years... that should tell you something!

C Tech is just the greatest...I had an unusual project, rebuilding a VW 1600 aircooled motor. Arnie worked with me throughout the process to make sure I got everything I needed. This is a wonderful shop. Honesty and experience at a fair price.

C-tech is the best! Great guys to work with, and they take pride in their work!

They go above and beyond for their customs. Their work and knowledge of motors is phenomenal

Engine builders in the Grand Rapids area, this place is the real deal. While every other machine shop told me they were not comfortable with the idea of modifying a small block Chevrolet intake manifold, literally the most common and historic engine to build, C-tech simply scratched their head at my absurd idea of putting a distributor hole in an LT-1 intake and said yup we can do that for ya. It takes real experience and pride in your capabilities to take care of your customers and take on a strange request. This is the only shop that would do it, and they did it with pride, a smile on their face, and at an absurdly fair price. Confidence in capabilities is an earned quality, and a rare one. It comes from hard work and a passion for doing your job well. In an age of everything is disposible and yes we can install Edelbrock blah blah I think I can spin a wrench its so relieving to know theres at least one place with the pride and capabilities to accommodate other real gearheads. I can guarantee there is no better place in this area to trust your hard earned passion for performance with.

Awesome people Ive brought 2 engines their with in a month

If you have questions, give Arnie a call. He will get you what you need.

Messaged about 6 places between here and Detroit and called a few others. Had only 2 reply, these guys and 1 other. That also e says something about their customer service, in process of rebuilding Chevy 305 and will be bringing head and block down here.

Great place for engine work!

Always good to me.
